<p>ZWO EAF (Electronic Automatic Focuser) &nbsp;is popular among astro-photographers, becasue it works OK and is relatively inexpensive. However, once it is attached to the focuser-axis after removing the turning knob of focusers, one looses the manual focus ability when no electricity is applied. &nbsp;</p><p>This is a 0.8 MOD gear with 54 teeth, which can be fitted on the EAF of ZWO for adding the auto-focus functionality (via ASCOM compatible software such as NINA, SGP,…, etc.), or wirelessly controlled focusing (via, for example, Tilta Nucleus-M wireless lens motor https://tilta.com/shop/nucleus-m-motor-kit-i/ ) &nbsp;via the 0.8 Mod gear system, and also allowing manual focus by simply disengaging the motor.&nbsp;</p><p>For installation, first fix one of the factory-provided flexible couplings via 2 grub screws on the 5mm motor axis, next push the 54T gear on the coupling and aligned the outer 2 holes of the coupling (with 2 grub screws inside) with 2 holes of the 54T gear. Finally, with the 2mm hex screwdriver inserted, slowly turn counter-clockwise of the 2 outer grub screws to fix the 54T gear on the coupling.</p><p>This motor assembly is then attached to the telescope via 15mm clamp system of photography.&nbsp;</p><p>Note: since the c-c distance of 2 fixing holes of EAF is 22mm, one possible candidate is “CAMVATE Simple 15mm Single Rod Clamp (https://www.prusaprinters.org/print/124287/edit)".</p>
